Working with PC CF10

Is PC easy to machine?

Machines cleanly with sharp, high-rake tools, high speed and low feed with air/mist cooling; anneal 1–2 h near 120 °C before/after cutting to avoid stress crazing, and never use aggressive coolants.

Can PC be welded?

Joins well by ultrasonic, hot-plate, laser and solvent/adhesive bonding (methylene-chloride or urethane/epoxy); avoid over-welding that traps stress, and dry parts first.

Can PC be formed, bent or molded?

Dry to <0.02% moisture (120 °C, 3–4 h) before molding at 280–320 °C melt / 80–120 °C mold; sheet thermoforms and cold line-bends easily with generous bend radii (>1.5× thickness cold).

What surface finishes work on PC?

Takes vacuum metallizing, hard-coat (silicone/acrylic) for scratch and UV protection, pad printing and paint with PC-compatible solvent systems; polish with fine abrasives and plastic compound, and avoid alkaline or ketone cleaners.

PC CF10 — frequently asked

What is PC CF10 used for?

PC CF10 is typically used for machine guards and safety shields, clear windows and glazing panels, lighting lenses and light pipes, electronic and instrument enclosures, medical device housings and battery and connector housings. In short: impact resistant; stiff.

What is the yield strength of PC CF10?

PC CF10 has a typical yield strength of 63 MPa (9.14 ksi) and a tensile strength of 105 MPa (15.2 ksi) — stronger than 74% of polymer grades. Strength varies by condition: see the 12 listed tempers.

Is PC CF10 easy to machine?

Reasonably — machinability is rated fair (50/100, worse than 73% of polymer grades). Machines cleanly with sharp, high-rake tools, high speed and low feed with air/mist cooling; anneal 1–2 h near 120 °C before/after cutting to avoid stress crazing, and never use aggressive coolants.

Can PC CF10 be welded?

Yes — weldability is rated very good (70/100). Joins well by ultrasonic, hot-plate, laser and solvent/adhesive bonding (methylene-chloride or urethane/epoxy); avoid over-welding that traps stress, and dry parts first.

What surface finishes work on PC CF10?

Takes vacuum metallizing, hard-coat (silicone/acrylic) for scratch and UV protection, pad printing and paint with PC-compatible solvent systems; polish with fine abrasives and plastic compound, and avoid alkaline or ketone cleaners.

Can PC CF10 be formed, bent or molded?

What is the maximum service temperature of PC CF10?

PC CF10 is rated for continuous use to about 120°C (248 °F), and briefly to 145°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
